Yeah I was super careful putting on the block on my (then $450) 5870 card. It went well, but if I can save me the hassle, I'm all for it. I only paid 780$ for the card, since I used the $30 off newegg promo. That's only $120 for the installed waterblock, and you also save on shipping since you don't need to order a waterblock separately.

Pretty good deal so far, as long as it works as advertised. I'll let you guys know when I get it.
